CC2530: UART communication between CC2530 and openwrt

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK

Hi All,

I have a customized board(ZC) having cc2530 and it's uart lines connected to linkit smart 7688 which is also mounted on ZC. 

I have one Zigbee switch(ZR) to communicate with cc2530. So whenever I press the switch(ZR),  ZC will respond.

Now I want to collect the logs in openwrt (on linkit smart 7688) for ZR activities.So please guide me to establish uart communication between cc2530 and openwrt.

( For now i can connect cc2530 with ztool and can see some logs.  If I use some serial terminal like termite or real-term then it's giving some hex value

but i need some decoded value So my program can understand the specific logs for ZR activities and write it 's status to a file)

Thanks,

Hardik

    There's a Z-Stack ZNP interface specification.pdf in document folder which shows you some details.

    Hi YK Chen,

    Thanks for your reply.

    I have connected cc2530 to my PC and using Tera-term to see the data but it's showing some junk value.
    Could you please let me know the format of data sent by cc2530 ?

    If it's some other format then we can convert it into suitable format to make the use of logs.


    I am just trying to compare the received data in z-tool and Tera-term.

    In Z-Tool it's showing something like this

    But when i close z-tool and connect to Tera-term then it's displaying some junk value as given below

    ( cc2530 working with baud rate 38400 So setting the baud rate for tera-term and z-tool accordingly)

    Also I want to know the meaning of z-tool logs as given below
    /*****

    *****/
    Is z-stack sending any command internally or something similar like that?
    really don't know how it's working, Request for some guidance.

    Thanks,
    Hardik

    The communication is MT command. You can refer to Z-Stack Monitor and Test API.pdf in Z-Stack document folder for details.
